Instructions
Cream Butter and Sugar
Preheat oven to 175C. In a large bowl, beat softened butter with an electric mixer until fluffy. Gradually add powdered sugar and continue beating for 3 to 4 minutes until light and creamy.
Add Eggs and Vanilla
Add eggs two at a time, beating well after each addition. Mix in vanilla extract. The batter will look slightly curdled at this stage which is completely normal.
Fold in Dry Ingredients
Sift together flour, cocoa powder, and salt. Fold the dry ingredients into the batter using a spatula until just combined. Gently fold in the chopped walnuts. The walnuts are essential for creating the fudge tunnel and should not be skipped.
Bake the Cake
Generously grease and flour a 12-cup Bundt pan. Pour batter in evenly and bake for 58 to 62 minutes. Do not use a toothpick to test doneness as the center should remain gooey. The cake is done when the edges pull slightly from the pan.
Cool and Unmold
Cool the cake in the pan on a wire rack for 1 hour. Then invert onto a serving plate and allow to cool completely for another 2 hours before dusting with powdered sugar and slicing to reveal the fudge tunnel.
